For these applications, and those below, the tank must be placed upon a very stable foundation.

Additionally they can be used to grow plants. Start garden seedlings. Crypts, grown with only "their feet wet," will flower and seed (sometimes).

You need a very tight fitting top (extra tank bottom # 2), but one could also raise crickets. That is more of interest to the herp crowd, but if one leaves some wet sphagnum moss in with the crickets, removes it to another tank after a couple of days and sticks a couple smoshed cooked peas in there for food and a toilet paper cardboard roll for shelter, the "pin-heads" or baby crickets will hatch out and shelter in the cardboard cylinder. Carefully shake the cardboard tube into a jar and feed surface feeders such as the golden wonder killies, half-beaks, butterfly fish...

When Indianapolis' Al Anderson spoke in Chicago about six weeks ago on live foods, he told of "recycling" three or four aged 55 gallon aquariums as worm farms. (He has a big basement and put those tanks by a wall on the floor.) They are full of worm bedding. As he got them going, he double cultured African red worms and Grindle worms on Purina Worm Chow. He can harvest a cup of worms at least every couple of days! (I'd run duct tape over the outside of that crack first.)

Worms are great fish foods in and of themselves. They are wonderful for conditioning breeders. Al is spawning and raising a lot of fish these days. Yes, there is some slicing and dicing to size.

In the cold weather we have had lately, I wonder if an old tank could be put over a plant (planted outside too soon, evidentally) which one feared for. We use those old ones for storage of paraphernalia, aquarium and possibly garden.

That's a nice thought about shipping it to Chi-town. More possible is tossing a word on the site of the Toronto Aquarium Society

Don't know if someone would have a use for it Don't feel personally rejected if they don't. It might be a possibility though.

I have picked up several aquariums, incidentally seen on garbage day, while going to work or elsewhere. One was in such bad shape, I put it back out - early - the next garbage day. Sure enough! Within minutes somebody stopped and picked it up!

I'm sure other uses for wounded tanks will come to mind. :)
